Pete,
No problem. It's what we're here for. The new auto-detection of SSL has worked pretty well so far and helped make things even better auto-configured. Sorry you ran into a minor issue in the process.
I would still highly recommend looking into redirecting the www version to non-www as that's good for a lot of reasons, not the least of which is SEO and better usability for your users (in case something is accidentally linking to the https://www. part of your site).
As always though, should you need anything else or have any feedback, just let us know.
Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
Alex
